为什么未填写必填字段时不显示验证消息？

Question

我有下面的注册表和 storeUserInfo() 来处理注册表。但是有一个问题，如果用户不填写participant_name和participant_surname字段，这是必填项，不会出现任何验证错误，它会出现：

{success: true, message: "success"}
message: "success"
success:true

所以，不要显示任何验证错误，它会显示一条成功消息，并且任何信息都插入到 db 中。

你知道问题出在哪里吗？

Answer 1

似乎您没有捕获验证器失败实例，它将忽略 $validator 变量并返回成功。你应该像这样抓住它

if($validator->fails()) {
   return \Response::json([
        'data' => [
        'message'   => $validator->errors(),
        'success'   => false
        ]
    ], 404);;
}

例如，您可以添加自己的自定义 JSON 响应。您可以从$validator-errors() 获取所有验证器错误，如果$validator->fails() 是真实的，请确保返回它
